摘要：

Volatilization represents a non-reactive loss mechanism for aqueous halogen biocides. Equilibrium volatilities, as measured by effective Henry's law constants, or effective dimensionless partition coefficients (m), for free chlorine and free bromine were estimated to be 0.0604 atm (m = 4.55 x 10(-5)) and 0.0293 atm (m = 2.21 x 10(-5)), respectively, at 20-degrees-C using a stripping column. A true Henry's constant of 0.0600 atm (m = 4.52 x 10(-5)) was estimated for HOCl by application of equilibrium data to the system. The effective Henry's constant for free chlorine (H(Cl)) is comparable to a previously published value determined under similar conditions. Prior to this investigation, no published values for a free bromine effective Henry's constant (H(BR)) were available.
